‘SunTan’ sunscreen bottle features printed sensors in the packaging to measure the user’s skin type, sun levels and calculate safe exposure times. The design of the bottle features a Smartphone-like interface which focus on usability as users can easily understand the relationship between ultra violet intensity and their distinctive skin type. A sensor in the packaging measures the user’s skin type by analysing the amount of light reflected from the skin. The product’s suitability to the user’s skin type is indicated, guiding the correct SPF factor. The smart packaging also calculates the maximum ‘safe’ amount of time in the sun by determining the user’s skin type and the strength of UV radiation. A timer on the bottle shows the amount of time left and alerts when the time is up. In the brand name‘S’ and ‘T’ are stressed because the brand name is a mixture of ‘Smart’ and ‘Suntan’. The small lines around the ‘S’ mean both sunshine and time. This concept was developed by students from Brunel University London in collaboration with Crown Packaging & The Centre for Process Innovation (CPI) .
